I think them being full open source is fairly recent; the clients have always been open but the server was closed and they were selling subscriptions. I heard it mentioned on a podcast recently and they said it was fully open source which surprised me lol. Looked into it again and quickly set it up on all of mine and my family's machines. Highly recommend it :flan_thumbs:
@geekgonecrazy I've been using it for months now and love it :flan_guns:
Most default Android dialers have SIP integration built in but they've also forked Conversations to add a proper dialer with dialtones so you can interact with automated phone systems through native XMPP. The app is called Cheogram and you can get a download link by joining the XMPP MUC and asking for it. I don't think it's fully released yet
